Abstract

Description

Videos of the numerical simulation of single drop impingement onto smooth, superheated walls. The videos show the following cases: axisymmetric (2D) and quarter drop (3D). Impact parameters such as initial drop diameter, impact velocity, and wall superheat are 1.14 mm, 0.54 m/s, and 9.8 K, respectively. Dimensionless numbers such as Reynolds, Weber, Bond, and Jakob numbers are 2230, 62.4, 0.6, and 0.13, respectively. The working fluid is perfluorohexane (FC-72) in a pure vapor atmosphere of the same fluid at ambient pressure. The simulations are carried out in OpenFOAM.
